Solution

The characteristics present in angiosperms but not gymnosperms are:

  1. Flowers: Angiosperms are flowering plants. They produce flowers as their reproductive structures. Gymnosperms, on the other hand, do not produce flowers. Their reproductive structures are cones.

  2. Fruit: After fertilization, the ovules of angiosperms develop into seeds and the ovary develops into a fruit, which encloses the seeds. Gymnosperms do not produce fruits. Their seeds are "naked", meaning they are not enclosed in a fruit.

  3. Sporophytes and Megagametophytes: Both angiosperms and gymnosperms have sporophytes and megagametophytes. However, the development and structure of these can be different in the two groups. For example, in angiosperms, the sporophyte is the dominant, visible part of the plant, while the megagametophyte is reduced to only a few cells within the ovule. In gymnosperms, the sporophyte is also the dominant part of the plant, but the megagametophyte is larger and more visible than in angiosperms.
